GAS TURBINE ENGINE WITH REGENERATION OF HEAT Russian patent published in 2002 - IPC

FIELD: mechanical engineering; gas turbine engines. SUBSTANCE: proposed gas turbine engine with regeneration of heat has compressor, combustion chamber, high-pressure turbine, power gas and air turbines and heat exchanger. Power air turbine is installed on one shaft with gas turbine being connected at outlet with gas space of heat exchanger. Inlet of air turbine is connected through air space of heat exchanger with compressor intermediate stage air takeoff space. Ratio of area of compressor passage at compressor inlet to area of compressor passage at place of air takeoff is 2-5. Ratio of area of neck of first nozzle assembly of power air turbine to area of neck of first nozzle assembly of power gas turbine is 0.5-1. EFFECT: increased power and efficiency of engine. 3 cl, 3 dwg
